Abstract

A new large area imager for X-ray crystallography is described based on active pixel sensor technology. In order to meet the demanding requirements for crystallography the detector is designed with real time correction for reset noise, nonlinearity, spatial uniformity and bad pixels. The design of the detector is described along with its operating characteristics including noise, DQE and quantum gain. We describe new techniques to rapidly calibrate and characterize the X-ray imager.
